Extract/Scan for numbers from multiple lines of strings

[pokerprof]

Hi All,

I would like to extract numbers (the data) obtained from a serial acquisition which will be shown in multiple line of strings:

$#pressure 20

!@temperature 100

#voltage 1.2

I want to extract 20,100 and 1.2 so that I can do further data manipulation. Should I use match regular expression ? I could not get a proper regular expression to extract the numbers.

Thank you !

There are several scan/match functions on the Strings palette. Match Pattern would probably fit your purposes best.

i used the format, but i am sure you can use regex...

Hi there! Yes your method works, but it would be better if we can keep all the data into an array separated to pressure, temperature and voltage since we are continuously acquiring data. 

Can we put it into array ?

Pressure   Temperature   Voltage

20                    100          1.2

21                    101           1.2

Whose method? You don't say who you are referring to (and if you don't quote at least part of a message, we don't know unless you tell us).

This is no time to keep your cards close to your chest, pokerprof .

Hi Cameron,

Haha I am referring to apok's method. 🙂

Attached is a sample VI that I use according to your method but I have yet able to put the data into arrays. Looking forward to your royal flush !

[apok]

you can apply this method...btw, you never said anything about an 'array' 

and if i had not read your mind again....you can put header strings and make it a 2d string array

pokerprof, I'd love to see what you've done, but could you send it up in LV 2012 format (many of us have not upgraded yet to 2013)? Thanks.

as camerond said...can you please post the vi in a lower version?

• work computer is v2012
• home computer is v2013

thanks!

Hi guys,

Attached here is the block diagram. 

I am using regular expression to extract the value at the end of each string.

I would like to put the value to their respective parameters (pressure,temperature etc.) under an array so that I can do further manipulation with the values.

Note that the values will be acquired continuously from a serial acquisition port.

Hope this is clear and thanks for ye helppp !
